The microorganisms used in the fermented soybean meal are bacillus, lactic acid bacteria and yeast.

The percentage ratio of microorganisms used in the fermented soybean meal is: Bacillus: lactic acid bacteria: yeast is 4:1:10.

The present invention also provides a method for preparing fermented broiler feed, characterized in that the preparation steps include:

Preparation of fermented soybean meal: three kinds of microorganisms bacillus, lactic acid bacteria and yeast were activated in proportion with brown sugar water for 3 hours, and the water temperature was 30°C. Spray evenly on soybean meal after activation, seal and ferment for 1-3 days.

Crushing of bulk raw materials: Weigh corn, wheat, soybean meal, DDGS, corn gluten meal, hydrolyzed feather meal, stone powder, calcium hydrogen phosphate, Liuhe broiler premix, fermented soybean meal, and put them into a grinder for crushing according to the ratio of parts by weight. During the pulverization process, the sieve of the pulverizer can preferably be 2.5-3.0mm;

Granulation: The preparation time is 90-100S, and the granulation is performed at 75-85°C.

The role of a large number of beneficial microorganisms in fermented feed is as follows:

1. Antagonize pathogenic microorganisms Beneficial bacteria can antagonize intestinal pathogenic bacteria, maintain and regulate intestinal microecological balance. the

2 Improve the internal and external ecological environment

Feeding fermented feed can significantly reduce the number of intestinal Escherichia coli, Clostridium perfringens, Salmonella,

Increase the probiotics in the body and reduce the potential pathogenic bacteria, so the number of probiotics in excreta and secretions increases, and the pathogenic microorganisms decrease, thereby purifying the internal and external environment and reducing the occurrence of diseases.

3. Enhance the immune function of animals. Beneficial bacteria can stimulate immunity, stimulate humoral immunity and cellular immunity by producing antibodies and improving phagocytosis.

Immunization can enhance the immune activity of animals.

4. Producing a variety of digestive enzymes Beneficial bacteria can improve animal production performance, which is an important performance aspect of producing a variety of digestive enzymes

now. It is reported that Bacillus subtilis has strong protease, amylase and lipase activities, and also has enzymes for degrading complex carbohydrates in feed, such as degrading pectin, dextran, cellulose and other enzymes, many of which are not available in animals. have enzymes.

5. Produce a variety of nutrients Beneficial bacteria can produce lactic acid, which can improve the utilization of calcium, phosphorus and iron by animals, and promote the absorption of vitamin D

It has the ability to decompose macromolecular substances such as proteins, carbohydrates, and fats, making fermented products rich in amino acids, organic acids, oligosaccharides, and other easily absorbed components.

6 for feed mildew

Bacillus had a certain inhibitory effect on all tested bacteria. Bacillus has a good inhibitory effect on Geotrichum candidum and Aspergillus niger, followed by Aspergillus flavus, Saccharomyces cerevisiae and Rhizopus, and poor inhibition on Penicillium. It can be seen that adding Bacillus to grain, feed and its products properly, It can prevent mildew and prolong storage time.

The working mechanism of fermented feed:

1. Biological oxygen capture, promotes the growth and reproduction of beneficial anaerobic microorganisms, and maintains the ecological balance of the intestinal tract;

2. Treat bacteria with bacteria, antagonize pathogenic microorganisms, enhance immune function, and promote disease resistance of fattening pigs;

3. Rich in vitamins and proteins, it provides some nutrients needed for fattening pigs;

4. Promote the intestinal development of fattening pigs and enhance the activity of digestive enzymes.

The effects of the fermented feed provided in this experiment are: 1. Increase feed intake and daily gain, reduce feed-to-meat ratio; 2. Improve feed utilization and promote digestion and absorption of nutrients in feed; 3. Enhance the immune function of chickens , Promote the disease resistance of chickens.

Detailed ways

Example 1:

400 1-day-old AA broilers with basically the same healthy body weight were randomly divided into control group and experimental group, and raised in the same chicken house environment. One group was fed with ordinary broiler feed, and the other group was fed with fermented feed with the same nutritional index. Determination is carried out regularly to study the influence of fermented feed on the growth indicators of commercial broilers. (See Table 1 for dietary formula)

Purpose of the experiment: To determine the effect of fermented feed on the growth process of broilers.

Experimental animals: Broiler chicken breed is Arbor Acres broiler chicken.

Experimental plan: 320 1-day-old healthy commercial AA broiler chickens were selected as experimental animals, and they were randomly divided into two groups: the test group and the control group, with 4 repetitions in each group. In the feed formula of the experimental group, 50 parts of fermented 46% soybean meal was used instead of ordinary 46% soybean meal, and the other raw materials were the same; capsule vaccine drinking water; 21 days old, Newcastle disease vaccine drinking water. The experimental period was 28 days, and the feeding management was carried out in accordance with the "AA Commercial Broiler Feeding and Management Manual".

Detection indicators: growth performance indicators, protein metabolism rate, ND antibody titer of broiler chickens, immune organ index and the number of lactic acid bacteria in the cecum.

Data processing and statistical analysis: SPSS11.5 and Excel statistical software were used to analyze the data, and the data were expressed as mean ± standard deviation (X ± S).

results and analysis

1. Effect of fermented feed on broiler performance

It can be seen from Table 1 that the feed intake and daily gain of broilers in the experimental group were higher than those in the control group, and the feed-to-meat ratio was lower than that in the control group.

Table 1 Effect of fermented feed on broiler performance

2. Effect of fermented feed on protein metabolism rate of broiler chickens

It can be seen from Table 2 that both the apparent and real metabolic rate of protein in the experimental group were significantly higher than those in the positive control group, with the apparent metabolic rate increased by 3.32% and the real metabolic rate increased by 4.51%.

Table 2 Effect of fermented feed on protein metabolism rate of broiler chickens

3. Effect of fermented feed on Newcastle disease antibody level in broiler chickens

        Table 3 Effects of fermented feed on Newcastle disease antibody levels in broilers

It can be seen from Table 3 that the anti-Newcastle disease vaccine antibody levels of chickens in the test group were higher than those in the control group, but the differences were not significant.

4. Effect of fermented feed on the immune organ index of broilers

Table 4 Effects of fermented feed on the immune organ index of broilers

It can be seen from Table 4 that the immune organ index of chickens in the test group is higher than that in the control group. It can be seen that feeding fermented feed can enhance the immune function of chickens and promote the disease resistance of chickens

5. Effect of fermented feed on the number of Lactobacillus in the cecum of broilers

Table 5 Effects of fermented feed on the quantity of cecal contents

It can be seen from Table 5 that the number of Lactobacillus in the cecum of chickens in the test group was higher than that in the control group, and the difference was significant. Broiler chickens fed fermented feed can increase the number of lactobacilli in their cecum, enhance resistance, and reduce morbidity.
